Dr Matteo Grilli achieves top NRF rating

A P-rating (Prestigious Awards) by the National Research Foundation (NRF) is the holy grail for all young researchers at all South African universities and across all disciplines. It is a valuable tool for benchmarking local researchers against the best in the world. But it is hard to come by. Only one or two researchers are normally granted this sought-after standing each year.

Dr Matteo Grilli, a young Italian historian from the International Studies Group (ISG), says he was “pleasantly surprised” when he recently got the nod from the NRF, attributing his P-rating to the “excellent training and support” that he received from the UFS, and specifically the ISG and its head, Prof Ian Phimister.

Unique achievement for ISG

What makes this achievement even more significant, is that the ISG produced another P-rated scholar a mere four years ago (Dr Daniel Spence in 2016).

“For Prof Phimister to produce two P-rated researchers in such a short time is really an unbelievable achievement. I am not aware of any other department at any South African university that could achieve this,” says Dr Glen Taylor, Senior Director: Research Development.

P-rating requirements

The NRF’s P category honours young researchers (normally younger than 35 years) who have held a doctorate or equivalent qualification for less than five years. Researchers in this group are recognised by all or the vast majority of reviewers as having demonstrated the potential to become future international leaders in their field based on exceptional research performance and output from their doctoral and/or early postdoctoral research careers.

UFS becoming a mecca for African studies

Dr Grilli produced his first book, Nkrumaism and African Nationalism: Ghana's Pan-African Foreign Policy in the Age of Decolonisation around two years ago, after being accepted as a postdoc scholar by the ISG in 2015.

This unique research centre was established towards the end of 2012, with the aim of attracting and recruiting high-calibre postgraduate students and postdoctoral fellows from all over the world to the UFS.

“Working at the ISG has undoubtedly been the best experience of my life and made me the solid scholar I am today. At the ISG, I found the best working environment you could possibly have in an academic setting, even compared to the Northern Hemisphere,” Dr Grilli says.

He believes the centre’s strength lies in the “exceptional exchange” that researchers have with their peers, allowing them to not only master their research subject but also to learn from other members’ research and methodologies.

“In my view, the ISG is concretely contributing to bringing the centre of African studies back to the African continent,” he enthuses.

Passion for Southern African politics

Dr Grilli specialises in the political history of Ghana and Southern Africa, focusing on transnational histories of African liberation movements, the history of Pan-Africanism, the Cold War and decolonisation in Africa, and the history of European migrations in sub-Saharan Africa (particularly Italian communities in Ghana and the Congo DRC).

He is currently working on a book project about the history of Pan-Africanism, Socialism, and Nationalism in Southern Africa, particularly in Lesotho, eSwatini, and Botswana.

Asked what advice he had for young researchers, he echoes the counsel he received from Prof Phimister at the start of his tenure at the ISG:

“Always aim high. Don’t be intimidated by the fact that there is a lot of competition in the academia, nor that you might be disadvantaged because you work in the Global South. If you work hard, your research will speak for itself and you will be able to publish solid works even in the most prestigious journals of the Northern Hemisphere.”

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
